Paulo Cesar Tabares-Velasco

Assistant Professor, Mechanical Engineering

Paulo Cesar Tabares-VelascoDr. Tabares-Velasco came to Colorado School of Mines after being a research engineer at the National Renewable Energy Laboratory (NREL) where he developed the simulation environment for NREL’s Smart Power Lab. He was a developer of NREL building simulation/optimization tool BEopt. Prior to that he was a postdoctoral researcher at NREL where he led NREL technical research on phase change materials in collaboration with the Department of Energy Building Envelope and Windows R&D program, Oak Ridge National Lab, and Fraunhofer CSE. He also validated and improved the finite-difference/phase change material (PCM) model in EnergyPlus and analyzed pre-cooling strategies in residential buildings to reduce electric peak demand.

Dr. Tabares-Velasco’s work at Penn State on vegetated roofs has been recognized with the 2009 Crosby Field Award, 2009 Willis H. Carrier Award and 2009 Best Poster Award by the American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE), the 2011 Green Roof Research Award of Excellence by Green Roof for Healthy Cities (GRHC) and an NSF video production. He was also a Student Project Engineer at the Industrial Assessment Center at Colorado State University (CSU), where he performed more than 20 energy assessment to manufacturing plants in Colorado, New Mexico and North Dakota.
